DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] As Figures 1 to 5 , Figure 7 shown, a burr removal device for the cut pipe nozzle of the present invention embodiment includes two bodies 1, and the two bodies 1 are arranged opposite to each other; a grinding belt 11 is installed inside the centers of the two bodies 1; a first roller 12 and a second roller 13 are rotatably connected between the two bodies 1; two first conveyor belts 14 are sleeved between the first roller 12 and the second roller 13; a plurality of short plates 15 are fixedly connected to the two first conveyor belts 14 respectively, and one side of the short plate 15 is convexly arranged; when deburring the cut pipe nozzle, taking the two bodies 1 as the main framework of the burr removal device for the cut pipe nozzle, the first roller 12 is connected to an external servo motor, and the output end of the servo motor drives the first roller 12 to rotate between the two bodies 1. The second roller 13 connected by the first conveyor belt 14 rotates synchronously with the first roller 12. A plurality of cut pipes are respectively placed between four pairs of opposite short plates 15. The convex arrangement on one side of the short plate 15 can stably load the cut pipes. As the first conveyor belt 14 rotates, it drives a plurality of cut pipes to be conveyed. When the cut pipes are conveyed between the two grinding belts 11, the two working grinding belts 11 sequentially grind the two ends of the plurality of cut pipes, replacing the traditional method of processing cut pipes one by one, and can quickly deburr the nozzles of a large number of cut pipes in sequence, improving the efficiency of deburring the nozzles of a large number of cut pipes.

[0024] As Figures 1 to 4 shown, a fixing plate 2 is fixedly connected to the top between the two bodies 1; a threaded rod 21 is threadedly connected to the inner wall of the fixing plate 2; the bottom end of the threaded rod 21 is rotatably connected to a first limiting plate 22; when conveying and deburring a plurality of cut pipes, according to the thickness of different cut pipes, the threaded rod 21 rotates threadedly on the fixing plate 2, thereby adjusting the height of the first limiting plate 22. The first limiting plate 22 fits on the surface of the plurality of cut pipes, realizing that the plurality of cut pipes can be limited by the first limiting plate 22 and the first conveyor belt 14 during conveying, so as to maintain the stability of the conveying of the plurality of cut pipes. At the same time, because the cut pipes are limited and conveyed by the first limiting plate 22 and the first conveyor belt 14, the cut pipes can be stably ground when conveyed between the two grinding belts 11.

[0025] As Figures 1 to 4 , Figure 6As shown, triangular blocks 3 are fixedly connected to both sides of the short board 15 respectively; friction plates 31 are fixedly connected to both sides of the machine body 1 near the grinding belt 11 respectively; when multiple cut pipes are conveyed, the two triangular blocks 3 are respectively fixed on both sides of the short board 15, so that each loaded cut pipe can be limited on the two triangular blocks 3 on the side where the two short boards 15 are close to each other. With the pressing of the first limiting plate 22, the stability of the conveyance of multiple cut pipes can be improved. Moreover, relying on the combination of the two triangular blocks 3 in an inverted V shape, it is applicable to the placement and limitation of cut pipes of different thicknesses, improving the stability when deburring the pipe orifices.

[0026] As Figures 1 to 5 As shown, a fixed seat 4 is fixedly connected to the center between the two machine bodies 1; a hydraulic cylinder 41 is fixedly connected to the top of the fixed seat 4; the output end of the hydraulic cylinder 41 is fixedly connected to a support frame 42; a second conveyor belt 43 is rotatably connected to the support frame 42; a transmission assembly is arranged on the first roller 12, and the transmission assembly is used to drive the second conveyor belt 43 to rotate; when deburring the orifices of the cut pipes, the fixed seat 4 is fixed at the center position of the bottoms of the two machine bodies 1, the hydraulic cylinder 41 is fixed on the fixed seat 4 and its output end is connected to the support frame 42, and the support frame 42 supports the two shafts of the second conveyor belt 43. Relying on the transmission assembly to synchronously drive the second conveyor belt 43 to rotate when the first roller 12 rotates, the upper surface of the second conveyor belt 43 is attached to the surfaces of multiple cut pipes, so that the second conveyor belt 43 conveys multiple cut pipes at positions close to the two grinding belts 11. Anti-slip pads are fixed on the surface of the second conveyor belt 43 to increase the friction with the surface of the cut pipes, realizing that the second conveyor belt 43 drives the cut pipes to rotate when the cut pipes are sent to the grinding belt 11 for deburring, so that the orifices of the cut pipes can be comprehensively ground, improving the deburring effect on the orifices. At the same time, when deburring cut pipes of different thicknesses, the output end of the hydraulic cylinder 41 drives the support frame 42 to slide and adjust the height, so that the upper surface of the second conveyor belt 43 is attached to the surface of the cut pipes, playing a role in adaptively adjusting the height of the second conveyor belt 43.

[0027] The transmission assembly includes a first wheel disc 5 and a second wheel disc 51; the two first wheel discs 5 are fixedly connected to the first roller 12; the two second wheel discs 51 are fixedly connected to the shafts of the second conveyor belt 43, and a belt is connected between the first wheel disc 5 and the second wheel disc 51, and the diameters of the first wheel disc 5 and the second wheel disc 51 are different; when the first roller 12 rotates, the two first wheel discs 5 on the first roller 12 rotate synchronously, and the first wheel discs 5 synchronously drive the second wheel discs 51 connected by the belt to rotate. Since the diameters of the first wheel disc 5 and the second wheel disc 51 are different, the second conveyor belt 43 will rotate faster than the first conveyor belt 14, so that when the cut pipes are sent onto the second conveyor belt 43, the second conveyor belt 43 can drive the cut pipes to rotate, improving the deburring effect on the orifices.

[0028] As Figures 1 to 3As shown, a guide plate 6 is fixedly connected to one side of the machine body 1, and the guide plate 6 is located between the two machine bodies 1; a connecting frame 61 is fixedly connected to one end of the first limiting plate 22 close to the guide plate 6; the bottoms of both ends of the connecting frame 61 away from the first limiting plate 22 are fixedly connected to the second limiting plate 62; when multiple cut pipes are fed, the guide plate 6 is fixed to the front end feeding position of the two grinding belts 11, and the multiple cut pipes are placed in turn on the middle end surface of the guide plate 6, and the connecting frame 61 is connected to the second limiting plate 62. The two No. 2 limit plates 62 at the bottom end of the frame 61 limit the height of multiple cut pipes. Whenever a short plate 15 rotates close to the guide plate 6, a cut pipe can be taken away by the protrusion of the short plate 15, and the cut pipe is placed on the No. 1 conveyor belt 14 for transportation, which plays a role in loading the cut pipes. At the same time, the No. 2 limit plate 62 can adjust the height according to the thickness of different cut pipes along with the No. 1 limit plate 22 connected to the connecting frame 61, so as to realize the synchronous adjustment of the height to adapt to the thickness of the cut pipe at the loading and conveying points.

[0029] Two temporary storage plates 7 are fixedly connected to one side of the guide plate 6 near the short plate 15; arc grooves are opened at the ends of the two temporary storage plates 7; when the cut tubes are fed, the two temporary storage plates 7 are fixed near the short plate 15, and one of the multiple cut tubes placed on the guide plate 6 will fall into the arc grooves on the two temporary storage plates 7, so that the cut tubes falling into the arc grooves are separated from the other cut tubes, and when the short plate 15 rotates to the temporary storage plate 7, the protrusion of the short plate 15 can take away the cut tubes in the arc groove, and the next cut tube falls into the arc groove and waits for the next short plate 15 to take the material, which plays the role of separating the cut tubes for single feeding.

[0030] like Figures 1 to 4 , Figure 7 As shown, a base 8 is fixedly connected to one side of the machine body 1 away from the guide plate 6; two cylinders 81 are fixedly connected to the top of the base 8, and the two cylinders 81 are relatively staggered; an air pipe 82 is fixedly connected to the cylinder 81; a pneumatic mechanism is provided on the machine body 1, and the pneumatic mechanism is used to squeeze gas to drive the cylinder 81 to extend and retract; after deburring the two ends of the cut pipe mouth, two stations are provided at the end of the base 8, a brush is connected to the output end of the cylinder 81 of one station, and the brush can be rotated electrically, and a round brush is connected to the output end of the cylinder 81 of the other station The diameter of the rod and the round rod is consistent with the inner diameter of the cut pipe. Both workstations are used to deburr the inner wall of the cut pipe in turn. The No. 1 conveyor belt 14 conveys the polished cut pipe to the end for unloading, and the unloaded cut pipe is delivered to the two workstations of the base 8 by the manipulator. The pneumatic mechanism rotates with the No. 2 roller 13, and squeezes the gas into the two air pipes 82 in turn to drive the two cylinders 81 to extend and retract. After being deburred by a brush at one workstation, the manipulator grabs it again and sends it to another workstation to be pushed into the inner wall of the cut pipe by the round rod for deburring, thereby deburring the inner wall of the cut pipe.

[0031] The pneumatic mechanism includes a fixed box 9, a connecting rod 91, a rotating disk 92, a hinge rod 93, and an extrusion assembly; the two fixed boxes 9 are respectively fixedly connected to the outer walls of the two bodies 1, and the two fixed boxes 9 are located above the base 8, and the air pipe 82 is connected to the fixed box 9; the two connecting rods 91 are respectively fixedly connected to both sides of the second roller 13; the rotating disk 92 is fixedly connected to one end of the connecting rod 91 away from the second roller 13; the hinge rod 93 is hinged to the rotating disk 92; the extrusion assembly is arranged on the inner wall of the fixed box 9, and the extrusion assembly is used to extrude gas into the air pipe 82; when the two air pipes 82 are ventilated, the two connecting rods 91 rotate synchronously with the second roller 13, and the rotating disk 92 connected to the connecting rod 91 drives the hinged hinge rod 93 to pull the extrusion assembly. The rotating disk 92 and the hinge rod 93 are eccentrically arranged, so that the extrusion assembly reciprocates to extrude the gas inside the fixed box 9, and the gas inside the fixed box 9 is introduced into the air pipe 82. The two hinge rods 93 connected to the two rotating disks 92 are staggered and pushed. When one hinge rod 93 pushes, the other hinge rod 93 pulls, so as to realize the function of driving the deburring of the inner wall of the cutting pipe.

[0032] The extrusion assembly includes a sliding block 94 and an extrusion rod 95; the sliding block 94 is slidably connected to the inner wall of the fixed box 9, and the sliding block 94 is hinged to the rotating disk 92 through the hinge rod 93; the extrusion rod 95 is fixedly connected to the sliding block 94; when the gas inside the fixed box 9 is extruded, the hinge rod 93 pulls the hinged sliding block 94 to reciprocate as the rotating disk 92 rotates. The sliding block 94 reciprocates on the inner wall of the fixed box 9 and synchronously drives the extrusion rod 95 to extrude and pump the gas inside the fixed box 9, so that the gas inside the fixed box 9 is extruded and introduced into the inside of the air pipe 82 for use, thereby driving the telescopic end of the cylinder 81 to expand and contract, and realizing the telescopic transmission effect of the two cylinders 81.

[0033] Working process: When deburring the cut pipe nozzle, two bodies 1 are used as the main framework of the cut pipe nozzle deburring device. The first roller 12 is connected to an external servo motor, and the output end of the servo motor drives the first roller 12 to rotate between the two bodies 1. The second roller 13 connected by the first conveyor belt 14 rotates synchronously with the first roller 12. Multiple cut pipes are respectively placed between four short plates 15 that are opposite to each other in pairs. The convex setting on one side of the short plate 15 can stably load the cut pipes. As the first conveyor belt 14 rotates, it drives multiple cut pipes to be conveyed. When the cut pipes are conveyed between the two grinding belts 11, the two working grinding belts 11 successively grind the two ends of the multiple cut pipes, replacing the traditional method of processing cut pipes one by one. It can quickly deburr the nozzles of a large number of cut pipes in sequence, improving the efficiency of deburring the nozzles of a large number of cut pipes; When conveying multiple cut pipes for deburring, according to the thickness of different cut pipes, the threaded rod 21 rotates on the fixed plate 2 in a threaded manner, thereby adjusting the height of the first limiting plate 22. The first limiting plate 22 fits on the surface of multiple cut pipes, realizing that multiple cut pipes can be limited by the first limiting plate 22 and the first conveyor belt 14 during conveyance, thus maintaining the stability of the conveyance of multiple cut pipes. At the same time, because the cut pipes are limited and conveyed by the first limiting plate 22 and the first conveyor belt 14, the cut pipes can be stably ground when conveyed between the two grinding belts 11; When conveying multiple cut pipes, two triangular blocks 3 are respectively fixed on both sides of the short plate 15, so that each loaded cut pipe can be limited on the two triangular blocks 3 on the side where the two short plates 15 are close to each other. Cooperating with the pressing of the first limiting plate 22, it can improve the stability of conveying multiple cut pipes. And relying on the combination of the two triangular blocks 3 in an inverted V shape, it is suitable for placing and limiting cut pipes of different thicknesses, improving the stability when grinding the burrs of the pipe nozzle; When grinding the cut pipe nozzle, the fixing seat 4 is fixed at the center position of the bottoms of the two bodies 1, the hydraulic cylinder 41 is fixed on the fixing seat 4 and its output end is connected to the support frame 42. The support frame 42 supports the two shafts of the second conveyor belt 43. Relying on the transmission assembly, when the first roller 12 rotates, the second conveyor belt 43 is synchronously driven to rotate. The upper surface of the second conveyor belt 43 fits on the surfaces of multiple cut pipes, so that the second conveyor belt 43 conveys multiple cut pipes at a position close to the two grinding belts 11. The surface of the second conveyor belt 43 is fixed with an anti-slip pad to increase the friction on the surface of the cut pipe, realizing that when the cut pipe is sent to the grinding belt 11 for deburring, the second conveyor belt 43 drives the cut pipe to rotate, so that the nozzle of the cut pipe can be comprehensively ground, improving the deburring effect on the nozzle. At the same time, when deburring cut pipes of different thicknesses, the output end of the hydraulic cylinder 41 drives the support frame 42 to slide and adjust the height, so that the upper surface of the second conveyor belt 43 fits on the surface of the cut pipe, playing a role in adaptively adjusting the height of the second conveyor belt 43; when the first roller 12 rotates, the two first discs 5 on the first roller 12 rotate synchronously, and the first discs 5 synchronously drive the second discs 51 connected by the belt to rotate. Since the diameters of the first discs 5 and the second discs 51 are different, the second conveyor belt 43 rotates faster than the first conveyor belt 14. Thus, when the cut pipe is sent to the second conveyor belt 43, the second conveyor belt 43 can drive the cut pipe to rotate, improving the deburring effect on the nozzle; when loading multiple cut pipes, the guide plate 6 is fixed at the front feeding position of the two grinding belts 11. Multiple cut pipes are sequentially placed on the middle end face of the guide plate 6. The two second limit plates 62 at the bottom of the connecting frame 61 cooperate to limit the height of multiple cut pipes. Whenever a short board 15 rotates close to the guide plate 6, a cut pipe can be taken away by the protruding part of the short board 15. The cut pipe is placed on the first conveyor belt 14 for conveying, playing a role in loading the cut pipe. At the same time, the second limit plates 62 can adjust the height according to the thickness of different cut pipes, and adjust the height synchronously with the first limit plates 22 connected by the connecting frame 61 to adapt to the thickness of the cut pipe at the feeding and conveying positions; when loading the cut pipe, two temporary storage plates 7 are fixed close to the short board 15. One of the multiple cut pipes placed on the guide plate 6 will fall into the arc grooves on the two temporary storage plates 7, separating the cut pipe falling into the arc grooves from other cut pipes. When the short board 15 rotates to the position of the temporary storage plate 7, the protruding part of the short board 15 can take away the cut pipe in the arc groove, and the next cut pipe falls into the arc groove waiting for the next short board 15 to pick up the material, playing a role in separating the cut pipes for single-piece feeding; After deburring the two ends of the cut pipe mouth, two workstations are arranged at the end of the base 8. The output end of the cylinder 81 of one workstation is connected to a brush, which can rotate electrically. The output end of the cylinder 81 of the other workstation is connected to a round rod, and the diameter of the round rod is consistent with the inner diameter of the cut pipe. Both workstations are used to deburr the inner wall of the cut pipe in turn. The No. 1 conveyor belt 14 transports the polished cut pipe to the end for unloading, and the unloaded cut pipe is sent to the two workstations of the base 8 by the manipulator. The pneumatic mechanism rotates with the No. 2 roller 13, and squeezes the gas into the two air pipes 82 in turn to drive the two cylinders 81 to extend and retract. After being deburred by the brush at one workstation, the manipulator grabs it again and sends it to another workstation to be pushed into the inner wall of the cut pipe by the round rod for deburring, thereby deburring the inner wall of the cut pipe. When the two air pipes 82 are ventilated, the two connecting rods 91 rotate synchronously with the No. 2 roller 13, and the connecting rods 91 connected to the connecting rods 91 The connected rotating disk 92 drives the hinged hinged rod 93 to pull the extrusion assembly. The rotating disk 92 and the hinged rod 93 are eccentrically arranged, so that the extrusion assembly reciprocates to squeeze the gas inside the fixed box 9, and the gas inside the fixed box 9 is passed into the air pipe 82. The two hinged rods 93 connected to the two rotating disks 92 are pushed alternately. When one hinged rod 93 pushes, the other hinged rod 93 pulls, thereby realizing the deburring transmission effect on the inner wall of the cut tube; when the gas inside the fixed box 9 is squeezed, the hinged rod 93 pulls the hinged sliding block 94 to slide back and forth as the rotating disk 92 rotates. The sliding block 94 slides back and forth on the inner wall of the fixed box 9, and synchronously drives the extrusion rod 95 to squeeze and pump the gas inside the fixed box 9, so that the gas inside the fixed box 9 is squeezed and passed into the interior of the air pipe 82 for use, thereby driving the output end of the cylinder 81 to extend and retract, thereby realizing the telescopic transmission effect of the two cylinders 81.
